The rear parktronic sensor in BMW 5 E60 is secured in a special seat under the rear bumper. Because the sensor has a latch-"check mark" and fixed on the wiring harness, it is not necessary to remove the rear bumper without having to remove the rear bumper. The bottom of the bumper is very easy to get eight bolts and three pitons. After that, you can easily disconnect the rear parktronic sensor itself.
